Egyptian judges vote against overseeing referendum

The head of Egypt's key association of judges says 90 percent of its members have voted not to oversee the nationwide referendum on the country's contentious draft constitution, due to take place this Saturday.

The move is unlikely to stop the referendum from taking place, but it casts doubt on the legitimacy of the constitutional drafting process. A faction of judges loyal to Morsi has said it would not boycott the vote

Meanwhile tens of thousands of Muslim Brotherhood supporters have gathered for a mass rally in support of the President in central Cairo.
